  • High pressure centrifugal fans
  • Can be mounted vertically
  • Can easily be connected to a door switch


ScreenMaster HD is a powerful air curtain with electrical heating. It may be mounted vertically besides or hung over the doorway. HD is recommendend for door heights 2.5 - 3.5 meters and is often installed in shopping malls and airports where the door heigh is higher than normal.


HD0 has no heating elements. It is often installed in premises with air conditioning.



Depending on the length, the HD has either 2 or 3 centrifugal fans. Fans and heating elements (if present) are mounted in a corrosion-proof hot-dip galavanized, powder coated sheet steel casting.




The HD is mounted above the inside of the gate, as near the top of it as possible. The whole width of the gate should be covered. The unit can be angled for optimum efficiency and can be recessed in false ceilings. Make sure the inlet air grid is not blocked. Using the supplied mounting brackets ensures enough room for the inlet air supply.



For vertical mounting a special mounting bracket, HDS, must be ordered. One HDS is needed for each HD that is mounted vertically. Due to the total weight on the bottom HD, the total installation should not exceed three units. The HD should be mounted as close to the opening as possible, in the door's full height. For best result the airflow should be broken by a wall/frame on the opposite side of the door.



Regulating equipment must be ordered separately. The speed regulator for the fan, HDR4, can control as many as 4 long or 7 short HD air curtains. The electric heating elements are controlled by a power selector HDEV. A door switch, HDGL, can be connected to one or two HDR4 to make the air curtain run with different speed when the door is open and when the door is closed. Alternatively, instead of ordering two HDR4, HDR42 which has two settings can be ordered. If only one HDR4 is used together with the door switch the air curtain only runs when the door is open and stops when the door is closed. HDEV can be connected to a thermostat like the SR122.
